PUMP-BUCKET.

Specicaton of Letters Patent No. 29,443, dated June 1, 1858.

T o all whom it may concern:

Be it known that I, EMMETT QUINN, of Trenton, in the county of Mercerand State of New Jersey, have invented a new and useful Improvement inPumps; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawing, forming part of this specification, inthe several figures ofwhich similar characters of reference denote the same part.

F igure l is a sectional view showing the interior of cylinder, airchambers and tubing. Fig. 2 is a side elevation of the pump. Fig. 3 is asection of piston, through its axis, on line :c m. Fig. 4; is a-sectionof piston through its axis on line 3/ y. Fig. 5 is a cross section ofpiston.

The nature of my invention consists in a peculiar construction ofpiston, the details of construction and operation being as follows.

In the drawing, C C are the cylinders of the pump, open at bottom, andeach containing a piston P, connected by rod R with a beam B, operatedby rods R, leading to the lever L. Above the cylinders are valves V Vheld in position by passing a pin 70 across the leather' connection, asseen in Fig. l.

The tubing T, which is designed to be of wood, fits at bottom into ametal shoe Si, having fianges for connecting it with the body of thepump, by wedges w, the joint being packed as shown at o. At a suitabledistance above the cylinders the tube T is tapped and the mouth of anair chamber A inserted, the said chamber being suitably secured upon theoutside of the tubing. Another chamber A, is attached to the oppositeside and above the chamber A, as shown in Fig. 1. Should the well be ofgreat depth the chambers may be attached in pairs or singly at suitableintervals upon the tube. But for ordinary depths the attachment figuredin the drawing is found to serve the desired purpose.

The pump is supported by the piece E which rests upon the bottom of thewell, the cylinders being submerged. Power is applied to the lever L,which causes the water to be forced upward as indicated by arrows. Theupper air chamber A serves to correct the irregularity of the upwardflow of iiuid and renders the discharge uniform.

The piston P is made up of a metallic core 7) and wooden plug c drivenin a recess cast in the side of the core. Around the core and plug isthe packing (l. Then this packing is of leather', it is held by nailsdriven into the plug c, as shown in Fig. 5. This wooden plug also servesfor the attachment of the valve by furnishing a substance into whichnails may be driven as shown in Fig. 3. In this particular there existsa great advantage over the ordinary construction, inasmuch as withoutthe plug the valve has to be secured by drilling holes in the metal corefor screws, and an entirely different arrangement has to be adopted forsecuring the packing. The piston rod R is attached to the centraldiaphragm e by a pin z' passing through it and the jaws of the rod. Theunder edge of this diaphragm is an arc concentric with pin z', whichrests upon lling m in the jaw, so as to take the pressure from the pinif and thus insure greater durability to the piston. Or the jaw may beso made that its bottoni will be in contact with the diaphragm, theobject being to transmit the pressure of fluid through the diaphragm tothe piston rod. The valve V is made up of two plates of metal n n. witha disk of leather or other elastic substance held between them byrivets, as shown in Fig. 4. The cent-ral diaphragm e runs up to withinthe thickness of the lower plate of the upper edge of the piston, asshown in Figs. 3 and 4, so that the valve when closed rests upon theupper edge of the diaphragm c. This prevents the wear which is caused tothe leather when the entire pressure forces the leather down upon theedge of the piston. These improvements in the construction of the pistonare favorable to economy of construction and to durability and possessdecided advantages over the ordinary construction.

The construction of the pump is economical and effective. It is notliable to get deranged, and is easily repaired when any of the parts areworn out.

The air chambers are designed to be constructed with cocks as shown inFig. 2. These cocks are to be operated from above. In winter they willbe left open so as to permit the water remaining in the pump to passoff, and thus prevent freezing. Should there be any leakage of the airchambers they furnish a means of discharging the water.

Having described my invention and the operation thereof7 I claiml. Thecentral diaphragm e having its under edge concentric with theconnectingpin of the rod and in Contact with the bottom y of its jaw, incombination with the Vvalve V', constructed and operating so that thediaphragm receives the pressure on the valve and transmits it directlyto the piston rod.

2. I also claim the combination of the dove-tail recess in the metalliccore With the plug penetrable by nails illing the same, for the moreeasy and economical attachment of the Valve and packing as hereinbeforedescribed.

In testimony whereof, I have hereunto signed my name before twosubscribing Witnesses.
